I just finished Stanford's Coding Together Assignment: 1 - Matchisimo!
Below is a snap shot of what my view from Xcode/iOS Simulator looks like, along with a closeup of the simulator and some of its code.
Below is the code for my implementation files: CardMatchingGame.m and CardGameViewController.m.

I am well aware there are probably better ways to do this but, hey, it works (I think) :>
What fun projects have you accomplished or cool things have you learned lately? Share in the Comments or
Tweet/
Instagram us, we'd love to hear! :> :> xoxo
Do what you love and never work another day in your life. Source
